I did rent a motorbike, but I should have bought one and then sold it later.
I should mention there's actually name brand stuff at Saigon Square. (I'm guessing you grabbed a North Face backpack.) You can just pick up a shirt at Saigon Square, or you could have one tailor made in D1. http://www.shopdung.com/ (Dung Tailor) has had a lot of positive reviews online. You might be able to find somewhere else with some better fabric (depending on what you want made) but their service seems to be quite reputable. I haven't had a chance to wear my shirts yet.
